My view on the Rush in Rio DVD is that it is definitely poorly recorded and mixed, but that it's an entire live Rush concert with a great set list and great energy, so I can live with the sound problems.
On top of reading some of the complaints about the sound quality/mix in the forums, I knew there was a problem when the first track, Tom Sawyer, had very boomy bass. Compared to a well mixed DVD like Clapton One More Car One More Rider, where the bass drum is tight, Neal Pert's bass drum sounded very loose and boomy.
The crowd noise is way too high, Geddy's voice is too low, and there are some other problems, so this is definitely far from a reference concert DVD. However, if you are a big Rush fan, I'd say it's still worth owning. The DVD is definitely a disappointment though, for what it could have been if done properly.
